Hi,
If your delta ran fine on 04.09.2013 and your system has been restore to 03.09.2013 then by running the delta info package now you cannot get data for 04.09.2013. This would take data from last successful delta time stamp that is after 04.09.2013.
You have to run repair full on calendar day selection for missing period i.e. 04.09.2013
Thanks
Kamal
